Reproduction and Life Cycle
Breeding Habits
Spawns in warm waters, often near the Gulf of Mexico and the Mediterranean Sea. Spawning typically occurs during specific times of the year, varying by region.
Development Stages
Larvae hatch in plankton-rich waters and grow rapidly. Juveniles develop distinct characteristics as they mature, gradually adopting the predatory lifestyle of adults.
Fecundity
Females can produce millions of eggs per season, releasing them into the water for external fertilization. The number of eggs can vary depending on the size and health of the female.
Maturity Age
Matures at 4-8 years, although this can vary between different populations and species of Bluefin Tuna.
